OPERATING INSTRUCTIONS
3-1. INTRODUCTION.
3-2. Each stored reading
includes all
information generated
by the 3480A/B including input voltage magnitude,
range,
function,
polarity, and overload. Two additional digits are
added to identify the reading number
(i.e.
numbers 1
through 50). All BCD
output lines
are isolated
from
the
3480A/B
input terminals. Tables
3-1 and 3-2
describe the
storage control signals and list the pin numbers of the
control
and data
signals at
the Storage Connector.
